A novel protoparvovirus species was identified in domestic cats. The virus was distantly related to the well-known feline (feline panleukopenia virus) and canine (canine parvovirus type 2) parvoviruses, sharing low nucleotide identities in the capsid protein 2 (less than 43%). The virus was genetically similar (100% at the nucleotide level) to a newly identified canine protoparvovirus, genetically related to human bufaviruses. The feline bufavirus appeared as a common element of the feline virome, especially in juvenile cats, with an overall prevalence of 9.2%. The virus was more common in respiratory samples (9.5%-12.2%) than in enteric samples of cats (2.2%). The role of bufaviruses in the etiology of feline respiratory disease complex, either as a primary or a secondary agents, should be defined.
一种新型的细小病毒属病毒在宠物猫中被鉴定出来。该病毒与众所周知的猫泛白细胞减少症病毒（feline panleukopenia virus）和犬细小病毒 2 型（canine parvovirus type 2）亲缘关系较远，衣壳蛋白 2 区的核苷酸同源性较低（<43%）。该病毒与一种新鉴定的犬细小病毒属病毒在遗传上相似（核苷酸水平上为 100%），与人类 bufaviruses 相关。猫源 bufavirus 是猫病毒组的常见成分，尤其是在幼猫中，总体流行率为 9.2%。该病毒在呼吸道样本（9.5%-12.2%）中的检出率高于肠道样本（2.2%）。bufaviruses 是否在猫呼吸道疾病的病因学中起作用，无论是作为主要还是次要因素，都需要进一步确定。
